I have to select which wards have patients with the same last name. I need to display the name of those patients and the IDs that come with them.
My query below works to give me the proper result:-
SELECT pt.NAME, pt.PATIENTID, pt.PATIENTID FROM PATIENT pt WHERE pt.NAME IN (SELECT pt.NAME FROM PATIENT pt GROUP BY pt.NAME HAVING COUNT(DISTINCT pt.WARDNO) < 2) AND NAME IN (SELECT NAME FROM PATIENT GROUP BY NAME HAVING COUNT(*) > 1)
It gives me the following result in the table:
Name | PatientID Jones | p10 Jones | p29
However, I want to display my results in the table like this and am not sure how.
Name | PatientID | PatientID Jones | p10 | p29
Assuming you expect no more than two patient ID values, then a simple aggregation can work here:
WITH cte AS ( SELECT NAME FROM PATIENT GROUP BY NAME HAVING COUNT(*) > 1 AND COUNT(DISTINCT WARDNO) < 2 ) SELECT NAME, MIN(PATIENTID) AS PatientID1, MAX(PATIENTID) AS PatientID2 FROM cte GROUP BY NAME;
Query for pair-wise relationships between rows for a SQL Server table, If the linked column value for a source row occurs just once or is not populated, Rows in the source table that do not link to other rows by a value, such as The next screen shot shows a data source for pair-wise linking that� SELECT column_name[, column_name] FROM table_list.

The order in which columns appear in a display is completely up to you: Use the SELECT list to order them in any way that makes sense. Following are two examples.
Thank you Tim. That aggregation did work and I did a little tweak to make it a lot cleaner. It works to display just the two PatientIDs which is what I need for now. My new query is as follows
SELECT pt.NAME, MIN(pt.PATIENTID) AS PAT, MAX(pt.PATIENTID) AS PAT FROM PATIENT pt GROUP BY pt.NAME HAVING COUNT(*) > 1 AND COUNT(DISTINCT pt.WARDNO) < 2
However, if I do have multiple PatientIDs I am curious what I would do.
How to Use Values from Previous or Next Rows in a SQL Server Query, The problem is that SQL queries perform operations on a row-by-row basis; accessing data on different rows at the same time requires the query to do some extra work. 007-rownumber-column-Next-Rows-in-a-Query-; The� It is to display the column data like that in the report. no adding the columns. i have one more flag, can i do the same in decode?

I have to select which wards have patients with the same last name.
Assuming patients are not duplicated, you can get the patient/ward combinations as:
select p.wardno, p.name, count(*) from patient p group by p.wardno, p.name having count(*) >= 2;
If you only want the wards, then you have one of the rare situations where
select distinct and
group by are appropriate:
select distinct p.wardno from patient p group by p.wardno, p.name having count(*) >= 2;
SQL UNION, UNION allows you to stack one dataset on top of another dataset. the results of one statement display in the same table as the results from the other statement. By: Douglas P.

The SQL UNION operator. SQL joins allow you to combine two datasets side-by-side, but UNION allows you to stack one dataset on top of the other.

- You need some sort of pivoting logic here, but my first question for you is what happens if a given name has three patient IDs? What about four?
- That is another part that I am curious about. if there were to be four different patient IDs, how would I display the shared Name with all 4 patientIDs next to each other in the table. However, in this instance, I do not need to do that.
